Patented Aug. 5, 1952 UNITED STATES PATIENT OFFICE nazon BLADE SECURING DEVICE Charles R. Bennett, Cleveland, Ohio Application April '30, 1948, Serial No. 24,353

This invention relates to razors, especially to the razor blade securing means of a razor. The present application is a continuation in part of application, Serial Number 685,841, filed July 24, 1946, upon a Razor, now Patent Number 2,575,539, dated November 20,1951. The general object of the present invention is to provide a novel, improved-razor blade positioning head that is characterized by its positive engagement with a razor blade and with the easy release of the blade from the head,

A further object of; the invention is to utilize an inexpensive spring member for retaining blade holding members together with a razor blade positively positioned therebetween.

v A further object of the invention is to facilitate shaving action by the contour of the blade holding members and by removal of shaving-soap and beard particles froml' engagement with the cutting portion of the razor blade.

Another object of the invention is to provide a spring for retaining razor blade holding means in engagement and to facilitate initial engagement of the spring withthe razor blade holding means.

1 The foregoing and other objects and advantages of the invention will be made more apparent as this specification proceeds.

Attention is now directed to the accompanying drawing wherein Fig. 1 is an elevation, partially in section, of a razor using razor blade positioning devices embodying the principles of the invention;

Fig. 2 is a bottom plan of the razor blade securing device of the invention;

Fig. 3 is an end elevation of the device of Fig. 2;

. Fig. 4 is a longitudinal section taken on line 4'-4 of Fig.3; and

Fig. 5 is an-elevation taken on line 5-5 of Fig. 3.

With particular reference to the details of the structure shown in the accompanying drawing; a razor including a tubular handle I is shown and it is provided with a tubular end or top member 2 that engages with one end of the handle I' by means of a friction joint. An end 3 is provided for the opposite end of the handle I. The handle I has an axially directed slot 4 formed therein, which slot has a pin 5 extending therethrough and connecting to a block I that is positioned snugly in the handle for axial sliding movement therein. As more completely explained and claimed in the above-identified patent application, a razor blade securing device Hill is adapted to be supported by the handle l.- Also, the head j "3 Claims. (01. 30-58) A 2 or device lllil is adapted to be received within the tubular handle I. To this end, a pair of resilient arms 8 are secured to the block I and extend therefrom for engagement-with the device IDO. The pin 5 may be used for sliding the block I axially of the handle I for exposing or retracting the arms 8, as desired so that the razor unit of the invention can be operatively or inoperatively positioned.

The salient features of the present invention reside in the details of the razor blade positioning device I00, previously referred to. This device I06 includes a small, flat, rectangular member II which has hinge eyes 12 formed therein or suitably secured thereto. This member II also has a lip I3 extending therefrom substantially normal thereto. A second relatively small, substantially flat rectangular member [4 also is provided and it has a pair of hinge eyes 15 formed therein, one at each end of same. The members ll and H! are adapted to receive a hinge pintle IS in the hinge eyes with the hinge eyes [2 being positioned immediately adjacent the inner ends of the hinge eyes IE to secure the members II and [4 together for relative pivotable movement therebetween.

A mounting bracket or flange I8 is provided on and usually formed integrally with the member M, which bracket extends substantially normally therefrom. This bracket l8 has a pin l9 extending therethrough substantially perpendicular thereto adjacent each end thereof. The pins l9 are adapted to engage with the spring arms 8 so as to position the device [00 on such arms 8 for use of the razor device. Normally one of such arms is permanently engaged with one pin It whereas the other spring arm would be temporarily engaged with the remaining pin l9 only when the razor device was operatively positioned.

As an important feature of the invention, a substantially arcuate leaf spring lfll is provided in the device I00 for resiliently urging the members ll and I4 into engagement. The spring llll has an aperture 102 formed therein adjacent one end thereof whereas a slot {03 is formed in the opposite end of the spring; The-spring 10! is adapted to be compressed between the lip l3 and the bracket l8. Engagement of the spring with these members is facilitated due to the fact that the slot I03 may be engaged readily with its associated pin I9 after which the spring l0! can be slid into its operative position between the lip l3 and bracket l8, and the hole I02 can be sneapped into engagement with its associated P n Figs. 3 and 4 best show that a pair of longitudinal directed slots I 04 are formed in the member I 4 adjacent the cutting edge of razor blade I0 which is positioned between the members II and I4. Thus when in use, shaving cream, hair particles, etc., that collect adjacent the end of the blade I0 and are forced in between same and the member I i, can flow therefrom through the slot or slots I04 provided in the member I4. The retention of the blade I6 in a desired position on the member I4 is facilitated by the formation of end flanges I 65 on the member I4. Retention of the razor blade Ii) in a desired position also may be expedited by the provision of alug I06 that extends outwardly from the surface of the member I4 and engages with a hole formed in the blade I9 and adapted to receive the lug I08 therein. Of course, the end flanges I65 and lug I06 may either or both be formed on the member II, when desired. In operation, member II is normally that at the top of the razor so that a-curved contact edge I9? is provided on the member I4 to facilitate sliding contact of the razor device I90 over the skin surface to be shaved.

Whenone desires to change the razor blade being used, all that i necessary to do is to grasp the handle and arms 8 and then depress the'lip !3 with the thumb or finger. Depression of the lip I 3 causes the members I! apart and the razor I0 will either fall from, or it can be shaken from engagement with the device Iilii. Any razor blade positioned in the device IBD will be continuously andautomatically retained therein by the locking action of the spring IOI.

In some instances, it may be desirable to retain a supply of extra blades in the end cap 2. Hence, blades I I8 are shown positioned therein.

The spring Hi l is also adaptedto facilitate r leaseof a razor blade and relative movement of themembers II-and It since the pin we normally is spaced from the inner end of the slot I03. Hence-the end of the spring iii may move longitu'dina'lly as the movement of the lip. I 3. Of course, the-spring IcI may be engaged with the members I I and I4 and pins I9 otherwise than as set forthherein, if desired.

From the foregoing, it will be seen'that an inexpensive, sturdy razor-blade securing device is providedby the invention and that a springis used effectively and continuouslyto retain a razor blade in operative position inarazorblade positioning device. I
